The failure response of aluminum alloys (Al-6061 and Al-7075) under the condition of simultaneously pre-stressing and laser heating was investigated. Specimens were subjected to predetermined preloading states and then irradiated by continuous wave fiber (Yb) laser. For all specimens, it was found that the yield stress decreased with increasing laser power density. This implies that the load-be...

The use of lightweight materials, such as ultra-high-strength aluminium alloys, is in high demand the automotive and aerospace industries where weight savings are critical. tool materials used for high-speed cutting these alloys subjected to severe conditions that promote premature failure tools. application polycrystalline diamond (PCD) coatings provides tools with increased mechanical thermal...

Abstract Aluminium-based alloy type 7075 is known for its good ductility, high mechanical strength, toughness and fatigue which why it mainly used in the construction of dynamically stressed parts structure airplanes, vehicles ships. Although has these qualities, at present behavior not been studied hydrodynamic stresses that allow to be work cavitation conditions, such as pump rotors boat prop...

In this paper, commercially cold-rolled and artificial aged EN AW 7075 T6 alloy has been used. To ensure increased corrosion resistance, surface hardness, scratching aesthetic features, aluminium was subsequently hard anodised hot-water sealed (AC-A). The anodizing sealing process hardness up to 304±13 HV 1 from an initial of 194±3 1. Also, the microhardness layer bulk material documented. Scan...
